Hi @SuperMerlin,

I didn't try your code yet.

But I don't understand this if-clause

  1.       if(app.version.match(/^\d+/) > 15) return selectedLayers ;  
  2.        }else{   
  3.            if(app.version.match(/^\d+/) > 15) return selectedLayers ; 

if version >15 do something

or

if version >15 do the same

???

If you look at the else code you will see the code uses a diffent method in not > 15 it does not return it continues on. Also the way JIVE messes up formatting it is difficult to see where the first If is in the scripts structure. IS that else for that fits if you show?

The function always returns selected layers the are three return point in the function.  Reformatted the function  you will see that else is not for the first if.

    Adobe Photoshop Scripting | Adobe Developer Connection 

    User here try to help you.  We all have different abilities.   You can use script other provide you should not expect that someone will be willing to program a script that will work with the next document structure you come up with and automate what you want to do.   You would need to design a script to implement your what you want to do.  You would need to design some document structure that would work with the script you designed and programmed.  Scripting is programming not a simple recorded and edit action.

    Script can be very powerful. If you look at a Plug-in script like Image Processor Pro you will see it contains 10,000+ lines of code that is not something you develop quickly.  Layer Comps to files is over 2,500 line of code and much more flexible then the custom script SuperM programmed for you.   Scripting is powerful programming a script is more work than you can handle. Scripting Photoshop is not simple and easy.  Some thing can be done with little code but thay are usually very simple and specific.

      JJMack​ These two script (this one, and last one you replied to earlier thread) i direly needed it! I use various script, and these are lot more fast even from photoshop actions.. I use them frequently in my work flow to deliver work to various clients.

      If you ask here User will tell you if it can be done with an Action the action will be fasteter than a script. Actions are canned Photoshop steps with the exception of a few conditional codition steps. They  have no plane text logic that  needs to be interpited into machine code and executed.  Action are faster than scripts. However they are not as powerful and flexable as a script can be. So yes you would need a script to loop through your document to do what you want.  If you were asking for help writting a script you will find many willing to help you learn Photoshop scripting better.

      IMO you have been very lucky that SuperM has done your work for you for free. You are not actually asking for help here which is what these forums are for. You are  asking for other to work for you for free for you are unable the do what you want to do and do not seem to want to learn.  For me that not what there forums were created for.  You most likely do not even read the code posted here for you.  You just use it and do not undetstans alert messages a script may give you. I hope your luck  will continues.  However if you come up with something that is very complex you will most likely fine you luck has run out.
